Abstract: <P>PROBLEM TO BE SOLVED: To provide a decomposition agent, which can maintain its high decomposition ability for decomposition of a fluorine-containing gas for a long time period and can be recovered after decomposition in a form applicable to recycling as a raw fluorine material.  <P>SOLUTION: A decomposition agent 2 comprising aluminium hydroxide, calcium hydroxide, and calcium carbonate decomposes a fluorine-containing gas by heating the gas. The surface is converted to aluminum oxide and calcium oxide by dehydration; these oxides, calcium carbonate, and water (steam) generated by dehydration react with the fluorine-containing gas, so that high decomposition ability can be maintained for a long time period. Also, improved decomposition ability decreases the exchange frequency of the decomposition agent 2, so that the operation efficiency of a decomposition apparatus 1 can be improved. Also, after decomposition, the decomposition agent 2 can be recovered in a form appropriate for recycling thereof as a raw fluorine material.  <P>COPYRIGHT: (C)2010,JPO&INPIT
